Injection Molding Parameters
Drying treatment: PPS shall be fully dried before processing. Recommended drying condition: 120‑140°C for 3‑4 hours.
Injection temperature: Molding temperature range: 285‑330°C.
Reference barrel temperature setting: ‑ Rear section: 280‑300°C ‑ Middle section: 300‑320°C ‑ Front section: 310‑330°C ‑ Nozzle: 310‑330°C
Mold temperature: Recommended mold temperature: 120‑150°C. Higher mold temperature contributes to better surface gloss and improved dimensional stability of molded parts.
